A sensor arrangement including at least one electro-optical sensor which is secured to a receiving structure of a sensor holder. The electro-optical sensor includes a sensor housing with an optically active sensor layer that is arranged thereon. The optically active sensor layer forms a light-sensitive plane. The sensor holder includes a non-adjustable receiving structure which compensates for a previously determined deviation in shape of the electro-optical sensor from a desired shape.

Sensor arrangement

A system that facilitates collecting data is described herein. The system includes a digital camera that is configured to capture images in a visible light spectrum and a near-infrared camera that is configured to capture near infrared images, wherein a field of view of the digital camera and the field of view of the near-infrared camera are substantially similar. The system further includes a trigger component that is configured to cause the digital camera and the near-infrared camera to capture images at a substantially similar point in time, and also includes a mounting mechanism that facilitates mounting the digital camera and the near-infrared camera to an automobile.

Examples of the present disclosure describe systems and methods for capturing data to acquire indoor and outdoor geometry. In aspects, a data capture system may be configured to acquire texture data, geometry data, navigation data and/or orientation data to support geolocation and georeferencing within indoor and outdoor environments. The data capture system may further be configured to acquire seamless texture data from a 360&#xb0; horizontal and vertical perspective to support panoramic video and images.

Vehicle-mounted sensor system that includes cameras and laser measurement systems

Mobile platforms are used to capture an area using a variety of sensors (e.g., cameras and laser scanners) while traveling through the area, in order to create a representation (e.g., a navigable set of panoramic images, or a three-dimensional reconstruction). However, such sensors are often precisely calibrated in a controlled setting, and miscalibration during travel (e.g., due to a physical jolt) may result in a corruption of data and/or a recalibration that leaves the platform out of service for an extended duration. Presented herein are techniques for verifying sensor calibration during travel. Such techniques involve the identification of a sensor path for each sensor over time (e.g., a laser scanner path, a camera path, and a location sensor path) and a comparison of the paths, optionally after registration with a static coordinate system, to verify that the continued calibration of the sensors during the mobile operation of the platform.

Mobile imaging platform calibration

Many imaging scenarios involve an achromatic image (e.g., a panchromatic image or a near-infrared image) and one or more concurrently captured monochromatic images (e.g., RGB images captured through a Bayer filter array), and the compositing of these images through de-mosaicing and/or pan-sharpening to generate a high-resolution color image. However, in many such scenarios, the monochromatic images may exhibit distortion of edge geometry, resulting in artifacts and/or color distortions near visual edges of the composite image. However, such distortions may be absent from the achromatic image, and edge geometry may be represented as an intensity gradient among respective neighborhoods of achromatic pixels. Presented herein are techniques for reducing such distortions in monochromatic images through iterative adjustment of monochromatic pixel intensity to reflect the gradients of the neighborhoods of the corresponding achromatic pixels. Convergence of such adjustments produces composite images exhibiting accurately reconstructed edge geometry.

Three dimensional image capture system for imaging building facades using a digital camera, near-infrared camera, and laser range finder

A digital camera described herein includes an analyzer component that analyzes a histogram of a first image, wherein the first image has a first resolution. The digital camera also includes a setter component that sets an exposure time for capturing a second image based at least in part upon the analysis of the histogram of the first image, wherein the second image has a second resolution, and wherein the first resolution of the first image is less than the second resolution of the second image.

Determining exposure time in a digital camera

A large format digital camera has a primary camera system configured for collecting panchromatic image data and two or more secondary camera systems configured for collecting color image data. Each of the secondary camera systems has an optical system that has a longer focal length than the optical system of the primary camera system. The resolution of each of the secondary camera systems is also greater than the resolution of the primary camera system. The footprint of images produced by the primary camera system is larger in size than the footprint of images produced by the secondary camera systems. Images produced by the primary camera system offer information for performing image-based georeferencing by means of photogrammetric triangulation. Images produced by the secondary camera systems offer a high-resolution narrow angle color image suitable for use in ortho image production.

Systems and methods are described herein that cause data from asynchronous data sources to be provided with a timestamp that corresponds to a common time base. A trigger board can be used to control synchronized data sources, and can generate timestamps when data is collected by the synchronized data sources. Unsynchronized data sources can generate data independent of the trigger board. System timestamps are generated each time data from the synchronized data source and the unsynchronized data source is received. Values of the system timestamp can be modified, and can be replaced by timestamps that correspond to the time base used by the trigger board.

Synchronization of multiple data sources to a common time base

Apparatuses and methods for enhancing a 'primary' large format, digital, macro-image with 'secondary' image data are provided. The secondary image data is collected utilizing one or more secondary optical systems having at least one electro-optical detector array (e.g., a CCD array) and a specific set of optical mirrors or optical prisms, arranged in such a way that the secondary optical systems extend the angular field-of-view of the primary optical system and the resultant digital image in at least two opposing directions, for instance, in the left and right and/or fore and aft directions. The primary image data and the secondary image data may be distinct and/or may include portions that overlap with one another. Further, the primary image data and the secondary image data may be collected at the same or different resolutions. The collected primary image data and secondary image data are utilized to generate a single output image.
